The device is configured to provide unmistakable, distinguished commands, without the need for verbal or visual instructions. The method also includes wirelessly communicating instructions to the device to activate at least four tactile stimulus components of the device thereby providing the set of distinguishable tactile instructions to the user.

FIELD OF THE INVENTION

The present invention relates generally to portable navigation devicesand methods, and more specifically to wearable devices for navigation.

BACKGROUND OF THE INVENTION

At present, extreme, sports and military navigation are practiced eitherby memorizing a route on a map, by holding and reading a physical map,or by following visual and/or sound directions of a given navigationcomputerized application. These available practices are not practicalfor certain types of extreme, sport and military navigation scenariosand conditions. Often, they are ineffective in directing the user to histarget accurately, on time and safely.

Most prior art systems relay and employ subjective skills such ascognitive abilities (e.g. intelligence, perception of space, naturalorienteering, etc.) and weak, easy to disrupted, senses such as visionand sound: The resulting navigation experience of prior art devices isthat they are demanding and often fail due to environmental disturbancesto the user.

The prior art technique of memorizing a route on a map is a practicewhich requires subjective orientation skills, intensive learning andtraining and considerable preparation time before the navigation.Moreover, while navigating on an unmarked route at natural/wild/hostileenvironments, it becomes a difficult task even for professionals.Mistakes and misdirection are common, obliging the hiker, athlete orsoldier to stop and open an actual map (or a computerized navigationapplication). This costs them time, disqualification in competitions andmilitary courses, their professional reputation, and may even creategrave danger at hostile military scenarios while stopping andilluminating the map.

Holding and reading a physical map is a practice which is impracticalfor sport, extreme and military navigation scenarios and conditions, asit requires the hiker, athlete or soldier to continuously stop and openan actual map and thus costing them time, disqualification incompetitions and military courses, their professional reputation, andmay cause grave danger at hostile military scenarios while stopping andilluminating the map.

Visual directions—as in holding and reading a physical map, thispractice is irrelevant for sport, extreme and military navigationscenarios and conditions as it requires the hiker, athlete or soldier tocontinuously stop and look at the actual map and thus costing them time,disqualification in competitions and/or military courses, theirprofessional reputation, and may create grave danger at hostile militaryscenarios while stopping and using an illuminated screen.

There are also several wearable devices offering visual basedindications for navigation (alongside vibration based indications).These applications hold the same described limitations and are even lesspractical as they employ tiny wrist-fitted screen, obliging the hiker,athlete or soldier to watch and focus on tiny visual indications whilethey are at a hectic environment requiring their optimal attention.

Verbal sound directions—this practice is irrelevant or less practicalfor sport, extreme and military navigation scenarios and conditions asit requires the hiker, athlete or soldier to focus on listening to theinstructions while they are at a noise-hectic environment and need to belistening to their sound-rich environment, such as radio communication,conversations, potential threats, targets, animals in hunting, theweather, and even music, in the case of some athletes.

Vibration directions—there are several wearable devices offeringvibration-based navigation. These ones namely offer a wristbandcomprising a plurality of haptic feedback devices arranged around acircumference of the wristband. This practice is irrelevant or lesspractical for sport, extreme and military navigation scenarios andconditions as the vibrating directions are of plurality of complexsensations imposed on one narrow area surrounding one hand and thus itrequires the hiker, athlete or soldier to be extremely focused on (andattentive for) various complex sensations pulsing on a narrow segment ofone of their hands: All that, while they are practically overwhelmed bystimulations from all senses all over their body (E.g. noises, rain,beatings, wounds, cold, heat, etc.) and by high-adrenaline sensationsand emotions (fear, pain, aggressiveness, etc.). In other words, in theintense context of real life the hiker, athlete or soldier act in, theypractically cannot differentiate between the concentrated vibrations andthus to translate the vibrations to actual directions; as the vibrationsare limited to a too narrow area on the wrist.

WO 2014099004A1 describes an apparatus, method and other techniques fora wearable navigation device. For example, an apparatus may comprise awristband comprising a plurality of haptic feedback devices arrangedaround a circumference of the wristband and logic to wirelessly receivenavigation information from a computing device and to output thenavigation information using one or more of the plurality of hapticfeedback devices, the output comprising a mechanical representation ofthe navigation information. Other embodiments are described and claimed.

There is therefore an unmet need of a device capable of providingunmistakable, distinguished directional commands, without the need forverbal and/or visual instructions.

FIG. 10C is a simplified schematic illustration of a side view 1050 oftactile instructions device 1000 of FIG. 10A, in accordance with anembodiment of the present invention. The device may have dimensions of14 cm in width, adjustable 10-50 cm in length, using a strap, like awatch strap, buttons, studs, Velcro or any other suitable fasteningmeans (not shown). The thickness of the device may be 1.3 cm.

Reference is now made to FIGS. 11A and 11B, which show a simplifiedschematic illustration of flowchart of a method 1100 for tactilenavigation instruction, in accordance with an embodiment of the presentinvention.

The user/team leader launches a navigation application in the smartphone 120, in a launching application step 1102.

He/she checks to see if there is an available “saved and complete” trek(route) in checking step 1104.

If yes, he proceeds to step 1106, if no, he has the options to proceedto edit a saved Trek route in an editing trek step 1108. He edits asaved trek (route) by either moving/deleting waypoint on map or by theediting tools in application's menu. He may optionally rename and/ordelete the trek.

In a saving trek step 1110, he saves the edited trek on the smartphone'sapplication.

Another optional step is to create a trek using a Google-generated map,waypoints and route (“search box”) in a trek creating step 1112.

Another optional step is to create a new trek by “drawing trek step1114” (route) by either (1) touching the map to set waypoints and/or (2)assigning coordinates

Another optional step is an import a trek step 1116 by importing one ormore of a map, waypoints and one or more route from external resourcesvia the internet on smartphone or via a removable SD card 120.

After steps 1112, 1114 or 1116, the user saves the trek in anothersaving trek step 1118.

Thus, he can now choose and “load trek” in a choosing and loading trekstep 1106.

The user may be alone, with a dog, or with a team/group. He thereforehas to choose the appropriate configuration for setting up the trek.

He opens a paring page in the application to define the number and typeof trek participants in a “choosing one or many step” 1120 (choose onedevice to pair (1:1) or one to many (1:M)?). Accordingly, he must choosehow many devices need to be paired. If there is a group of trekparticipants, he asks the group members to switch on theirportable/wearable devices 110, 700, 910 in an activating devices step1122. Thereafter, he proceeds with the method of FIGS. 12A and 12B,described hereinbelow.

If the user is to use a wearable device for the trek, or for example adog 1402 is to wear a device 1400, then the user activates the device instep 1126 and pairs it with his device via the application in smartphone120 (FIG. 1). If there is no wearable device to pair, then he proceedsto a starting trek step 1134. He then navigates “traditionally” per theapplication's visual and/or sound directions in a traditional navigatingstep 1136.

If there is a paired device, then he puts a device 1400 on his forearm(or on the dog's back (FIG. 14)) in a putting on step 1128.

He then clicks “start trek” on device 1400 or portable devices 110, 700,910.

He navigates by sensations per invention's navigational methodology, itsdirection's touch language and by its intuitive UX in a navigating step1132.

In an activating step 1140, he then click “start trek” on the cellphoneor wearable device. The wearable device begins to provide tactileinstructions to the. user, man or dog, that moves, in accordance to thewearable device's directional instructions towards the Start point(First waypoint). Once reaching the first waypoint, the user receives anotification alert in an alerting step 1142; “you have reached the startpoint (first waypoint)” by means of two calibration cycles andactivation of the appropriate directional arm (vibrator and/or LEDs) todirect the user to right path to head towards a second waypoint.

The user (and optionally a dog) move towards the second waypoint. Hethen receives directional alerts in a second alerting step 1144. Forexample, before a new waypoint, the portable device emits four shortbursts (light and vibration) in another attention alerting step 1154—4bursts in one and a half (1.5) seconds, on an appropriate directionalarm of the device—indicating the correct path and direction towards thenext imminent waypoint.

When the user diverts from his route/azimuth, he receives a correctionalert in a correcting step 1146. For example, the portable device emitsfour short bursts (light and vibration) for one and a half (1.5)seconds, on the relevant directional arm of the device, indicating therequired correction angle.

If, for example the diversion is extreme (10-15 meters diversion), aSTOP alert is triggered: One long burst (1 second)—All vibratorstogether (the system's STOP alert) and a STOP sign on the device screen,followed by a correction alert on the relevant arm of the wearabledevice indicates the correction azimuth/direction to be followedimmediately by the user.

When the user actually reaches the correct waypoint, he/she receives a“turn now” instruction in instructing step 1150. For example, thewearable device provides a “TURN NOW” alert of two long bursts (lightand vibration)—one (1) second each. to indicate the path/angle ofmovement towards the next waypoint in the trek.

Moreover, further alerts are provided in alerting step 1156, when movingat up to 6 Kph (walking)—10 meters before the next notification alert,alerting step 1158, At 7-12 Kph (run)—20 meters before the next turn,and at 13<X Kph (cycling, driving)—30 meters before the next turn,alerting step 1160.

When reaching a final destination a notification alert step 1152indicates that the user has reached an end point (last waypoint). Forexample, two STOP orders, one calibration cycle and a STOP sign on thedevice's screen.

Throughout the trek, the available directions/azimuths are identified bylight and vibration on the relevant arm of the wearable device, by theuser in alerting steps 1148. These include Forward (FW); Backward (BW);45° right; 90° right; 45° left; 90° left; “half turns” between the basicarms (The 22.5° directions/azimuths).

Reference is now made to FIGS. 12A and 12B, which show a simplifiedschematic illustration of flowchart of a method 1200 for group tactilenavigation instruction by a team leader, in accordance with anembodiment of the present invention.

In an opening pairing page step 1202, the leader/user opens a paringpage on application on smartphone 120 and he/she chooses the “One tomany (1:M) configuration”.

Thereafter, all members in the group switch on their portable/wearabledevices 110, 700, or 910 in an activating step 1204.

These devices will be listed on a pairing page of the application onSmartphone 120, in a listing step 1206.

In a checking step 1208, the devices listed in step 1206 and recognized,are checked to see if they have been used as paired before.

If yes, the user can now choose the devices to pair to; a) one by one,b) pair all or c) pair a selected few, in a choosing pairing techniquestep 1222.

Once paired, the user may name the paired device with an understandablename (e.g. number or name of the user who is to wear the device) in anaming step 1212.

Once paired, the named devices appear on the app in an uploading devicename step 1224, either on a map page (FIG. 15B) and/or on the Menu (FIG.15A): The leader's icon 1554 looks a bit different than the other groupmembers' icons 1552. Once paired, the devices may be (per device) set toreceive directional alerts (as of the leader) or only to alert ofseparation/split (step 1226).

The leader may wear the device on his forearm, the users may put ontheir devices and/or a device may be put on dog's back in a wearing step1228.

The group is now ready to go and the leader click a “Start Trek” buttonon his device in a starting trek step 1230.

In a testing device step 1232, it is checked to see if all devices areset to receive directional alerts. If yes, all group members navigatestogether as one by sensations per invention's navigational methodology,its direction's touch language and by its intuitive UX, in a directingstep 1236.

If no, group members are led by team leader who navigates by sensationsper invention's navigational methodology, its direction's touch languageand by its intuitive UX, in a leading step 1234.

Thereafter, it often occurs that team member(s) are out of (pre-set)range of communication (Bluetooth, Low Energy Bluetooth, RF, WiFiother), thus are separated/detached from the group, in a “lose part ofthe group step” 1238.

In a stopping step, 1240, the leader and the detached user(s) both get a“Stop” alert (all vibrators at once) twice on their portable devices,AND the icon(s) of the separated user(s) turns red on the Applicationmap screen and Menu on smartphone 120 (FIG. 1).

The leader tries to regroup by trying to minimize the distance from thedetached user(s) and/or in an attempting to regroup step 1242 byclicking on the red icon(s) of the separated user(s) on the application.This allows the leader to; (1) Know who is the separated user (theirassigned name or number) (2) Connect—Try to manually reconnect with theuser's device if the auto connections fails (3) Forget—Un-pair thedevice and the application (4) Rename—When/if the device will be used bya different person (5) Delete—The device will be deleted from the App'slogs (will require a new pairing process if tries to re-pair). It isrelevant too, when a device has a fatal technical issue.

In a regrouping step 1244, when the team regroups, the detached userwill receive a “Calibration” alert and the Leader will receive a“Calibration” (full cycle of vibrations) AND a directional alert toindicate and lead the Leader to the next waypoint.

Thereafter, in a continuing the trek step 1246, the group continues thenavigation.

Reference is now made to FIG. 13A-13E, which are simplified screen shots1300, 1310, 1320, 1350, and 1370 on touch-screen 202 of the tactileinstructions device 700 of the system of FIG. 1, in accordance with someembodiments of the present invention.

Screenshot 1300—Start your trek-opening screen. After pairing theapplication on the mobile communication device 120 (FIG. 1) and thetactile instructions device 700, clicking “Start your trek” will beginthe navigation via device 700. Typically it will show a text 1304, apicture or image 1302 and an on/off button 1306. The embeddedapplication then leads to a second screen 1310 “the environment”.

Environment-second screen 1310: Presents a compass (center arrow) 1318,a time of day (“Time”) 1320, an ambient temperature (“Temp.”) 1312 orother temperature 1314, an elevation (shows the degree of elevation1322—up or down shown by an arrow—of current location versus a nextwaypoint, an altitude 1316 above sea level.

This leads to a third screen 1320—a navigation screen, which presents abearing in degrees 1338, a speed of the user 1322, a current longitude1336, a current latitude 1334, Play/Pause 1332 and stop of thenavigation, enabling the user to set a new waypoint (on the go) byclicking the set landmark button 1330. The new Waypoint will be added tothe Trek and the system will lead the user from the newly createdWaypoint to the next one.

This leads to a fourth screen 1350 Trek's Distance, which presents acurrent distance from a start point 1356, a current distance from a lastway point 1352, a current distance to the next waypoint 1358 and aremaining distance to a destination (final waypoint) 1354.

This leads to a fifth screen 1370 (Trek's Time) and presents a runningtime from a start point 1376, a running time from a last waypoint 1372,a remaining time, per average speed of the user to a next waypoint 1378and a remaining time to a final destination 1374.

Reference is now made to FIG. 14, which is a simplified schematicillustration of a tactile instructions device 1400 on a dog 1402, inaccordance with an embodiment of the present invention. The devicecomprises a number of straps 1412, 1416, attached to arms 1410 of thedevice. for attaching it to the dog's body.

Dog Handling and Direction—

Visually-impaired user support—The current practice of a guide dogsupporting a visually impaired person is primarily of helping the personto avoid obstacles. With a device of the present invention placed on thedog's back, and with basic training, the dog may now lead the visuallyimpaired person to its destination and thus to become a completesolution of both leading and guiding.

Police, rescue and military support dog—the current practice of asending a dog to a remote task is by either walking next to it or byplacing a camera and speaker from which the handler is commanding thedog: Walking next to it—places the human handler in harm's way and thusundermine the reason for the usage of police/military dogs. The priorart practice of placing a camera and speaker on a dog is as with humannavigators. The practice employs sound directions, on which the dogshould rely. These employ the weak, easily disrupted, senses, such asvision and sound. These result in a navigation experience that isdemanding and subjected to environmental disturbances. With a device ofthe present invention device placed on the dog's back, and with basictraining, the dog may now be directed to the destination without a humanescort or by the easy to be disrupted sound directions.

Memory-disabled user support (e.g. Alzheimer's disease)—weary ormemory-disabled people may be supported by the device of the presentinvention. There is no need to remember the way home. Simply wear it onthe forearm and be led home.

In summary, the devices of the present invention are constructed andconfigured to provide a user with:

-   -   a) distraction-free navigation—no need to stop and open a map;        no need to be focused on complex signals on a limited body area        (e.g. wrist);    -   b) night-time navigation—by eliminating the need to stop and        open an illuminated map;    -   c) sensation-based directions only—the device of the present        invention uses the sensation of touch to guide and direct. It is        a much more deep and basic sense and less subjected sense than        the senses of vision and sound. And thus, when under external        stimulations, pressure, harsh field conditions, the elements,        etc., a user of the device of the present invention can        comprehend the instructions (in contrast to the users of        traditional navigation tools, which tend to fail;    -   d) the devices provide intuitive navigation—by a simplified        wearable directions' system, method and methodology;    -   e) Limited sensation types—Only vibrations and/or flickers (no        sound or graphics)    -   f) Sufficient physical distance between the sensation generators        (E.g. micro-vibrators and LED emitters) for distinguishing the        directions.    -   g) Less time needed to memorize the route—The practical nature        of the invention reduces the need to memorize the map or even to        look at the map before the navigation    -   h) Like no other, the devices of the present invention are        Forearm-mounted—leaving ones hands totally free for the task.        Multi-sensory—it ergonomically vibrates and flashes to guide        you; Simple—it has everything you need and nothing you don't;        Shockproof & water-resistant—it's designed and built to        withstand harsh environments; Intuitive design—easy to        understand and operate; Safe, distraction-free navigation—no        need to stop and look at a map or focus on complex signals;        Covert night-time navigation—disable the flicker indications to        remain night-covert; Long battery life—20 hours' in normal usage        and rechargeable.    -   i) The device of the present invention holds innovations in the        domains of Operational Design, User Experience (UX) practicality        and Navigation Methodology:    -   j) Its revolutionary 6 directional arms' operational layout is        geared to achieve optimal distance between the sensations,        enabling the user to easily differentiate between the physical        directions' instructions. And, to provide 360° bearing coverage.        There are micro-vibrators placed on the tip of each directional        arm and the vibrations are ergonomically funneled to a specific        point on the users forearm; resulting in a feel akin to being        poked in the skin, as someone is physically pointing and leading        you.    -   k) This extraordinary layout creates a natural, intuitive User        experience (UX) as the user can immediately use it without        studying or training. During extensive testing, the users'        comprehension was found to be immediate.    -   l) The revolutionary design and intuitive UX combination yields        an efficient, practical navigation Methodology by which, and        based on the speed of the user, the device of the present        invention will physically indicate and alert the user before a        required turn on where to head on.

The present invention provides systems 100, 900 and methods 1100, 1200for intuitive navigation at sport, extreme and military scenarios andconditions.

The present invention relates generally to wearable navigation devices110, 300 and methods, and more specifically to methods and systems forwearable navigation forearm-band for intuitive navigation at sport,extreme and military navigation scenarios and conditions.

The present invention is a wearable navigation forearm-band that guides& leads the user (or a group of users) such as a hiker, hunter, athleteor soldier to his/hers destination without distractions and with optimalconsiderations to the extreme circumstances and conditions the user isexperiencing.

Directions Methodology—A New Language

Notification Alerts;

Reached Start point (first waypoint)—Two calibration cycles and therelevant directional arm to direct the right path to head towards the2nd waypoint.

Reached End point (last waypoint)—Two STOP orders, one calibration cycleand a STOP sign on the device's screen.

Based on the speed of the user, the device alerts the user in advanceand before a required turn. Here's how:

Attention Alert;

Before a waypoint, 4 short bursts (light and vibration)—4 bursts in oneand a half (1.5) seconds, on the relevant directional arm: Indicates thecorrect path towards the imminent waypoint.

In up to 6 Kph (walk)—10 meters before the next turn;

7-12 Kph (run)—20 meters before the next turn; and

13<X Kph (cycling)—30 meters before the next turn.

Turn Alert;

When reaching the actual waypoint, there is a TURN NOW alert of two longbursts (light and vibration)—one (1) second each. To indicate the pathtowards the next waypoint.

Correction Alerts;

When the user diverse from route/azimuth—

4 short bursts (light and vibration) for one and a half (1.5) seconds,on the relevant directional arm—indicating the required correctionangle.

If the diversion is extreme (10-15 meters diversion), a STOP alert istriggered: One long burst (1 second)—All vibrators together (thesystem's STOP alert) and a STOP sign on the device screen. Additionally,the relevant arm will indicate the correction azimuth/direction.

The five basic directions/azimuths; identified by light and vibration onthe relevant arm. As exemplified in FIGS. 6 and 7. If the user needs toturn right 45 degrees, vibrator 604 vibrates. If the user needs to move90 degrees to the right, vibrator 606 vibrates. If the model device is300 (FIG. 3B) having lights and vibrators, then the appropriate lightsand/or vibrators are activated to provide a command.

If the user wears device 910 (FIG. 9), then, for example to move 22.5degrees to the right, arms 906 and 904 will vibrate alternatively. Alldevices of the present invention are constructed and configured toprovide the following commands to the user by tactile and/or lightinstructions: forward (FW), backward (BW), 45 degrees right, 90 degreesright, 45 degrees left and 90 degrees left.

Commands to move at an angle between the above angles are provided byvibration/lighting of two adjacent arms, such as a 22.50° move command:

Attention alert; before a turn, two (2) short bursts (light andvibration)—four (4) bursts in total in 1.75 seconds, on the two relevantdirectional arms. For example, in a case where a 22.50 turn to the rightis required, the FW arm and the 45° to the right arm will alternativelyblink and vibrate.

Turn alert; TURN NOW—2 long bursts (light and vibration)—4 bursts intotal in 3 seconds (0.75 each), on the two relevant directional arms.For example, in a case where a 22.5° turn to the right is required, theFW arm and the 45 degree to the right arm will alternatively blink andvibrate 2 times each.

BEST MODES OF IMPLEMENTATION

The present invention provides systems and methods for intuitivenavigation and thus is best implemented in the following examples ofnavigation modes:

Sport/Extreme Navigation (Day/Night)

-   -   a. Sport navigation—The user is subjected to time constrains,        harsh field conditions and the elements.    -   b. Hiking—The user is subjected to harsh field conditions and        the elements and carries heavy equipment.    -   c. Hunting—The user is subjected to harsh field conditions and        the elements, carries heavy equipment and needs to be attentive        to the surroundings.    -   d. Wind surfing—The user is subjected to waters conditions, the        elements (and sometimes time constrains), holding and steering        the board and needs to be attentive to the surroundings    -   e. Kayaking—The user is subjected to waters conditions, the        elements (and sometimes time constrains), holding and steering        the board and needs to be attentive to the surroundings.    -   f. On/Off-road Running—The user is subjected to time constrains,        complex and/or harsh road/track conditions and the elements.    -   g. On/Off-road Cycling—The user is subjected to road/track        conditions, the elements and time constrains, holding and        steering the bicycle and needs to be attentive to the        surroundings.    -   h. Mountain climbing—The user is subjected to harsh field        conditions and the elements, carries heavy equipment and needs        to be attentive to the surroundings.    -   i. Military navigation (Day/Night)—    -   j. The user is subjected to harsh field conditions and the        elements, carries heavy equipment , time constrains, needs to be        attentive to the surroundings and to stealth requirements    -   k. Assisting visually-disabled/blind users    -   l. A visually disable or blind person may find the systems and        devices of the present invention very useful in assisting        him/her in getting around. The user is subjected to varied        terrains and needs to be attentive to the surroundings.    -   m. Casual urban navigation    -   n. The user is in ant unknown area, maze-like streets, time        constrains, usually is an inexperienced navigator.    -   o. The user is subjected to the elements, carries equipment,        time constrains, needs to be attentive to the surroundings.    -   p. Dog handling and direction    -   q. Visually-impaired user support—the current practice of a        guide dog supporting a visually impaired person is primarily of        helping the person to avoid obstacles. With a device of the        present invention placed on the dog's back, and with basic        training, the dog may now lead the visually impaired person to        its destination and thus to become a complete solution of both        leading and guiding.    -   r. Police, rescue and military support—the current practice of a        sending a dog to a remote task is by either walking next to it        or by placing a camera and speaker from which the handler is        commanding the dog: Walking next to it—places the human handler        in harm's way and thus undermine the reason for the usage of        police/military dogs. The prior art practice of placing a camera        and speaker on a dog is as with human navigators. The practice        employs sound directions, on which the dog should rely. These        employ weak, easily disrupted, senses, such as vision and sound.        These result in a navigation experience that is demanding and        subjected to environmental disturbances.    -   s. With a device of the present invention device placed on the        dog's back, and with basic training, the dog may now be directed        to the destination without a human escort or by the easy to be        disrupted sound directions.    -   t. Memory-disabled user support (e.g. Alzheimer's Disease)    -   u. Weary or memory-disabled people may be supported by the        device of the present invention. There is no need to remember        the way home. Simply wear it on the forearm and be led home.

The systems of the present invention overcome the prior art requirementsfor visual and auditory directions as well as the requirement to holdand read a physical map in practice. Moreover, using the systems of thepresent invention, there is no longer a need for sound directions. Thusthe user, does not need to focus and listen to the instructions while ata noise-hectic environment (from radio communication, conversations,potential threats, targets, animals in hunting, the weather, and evenmusic, in the case of some athletes).

The systems of the present invention overcome the prior art requirementsfor using the prior art navigation gadgets. There are few gadgetsemerging offering vibration-based navigation. The more relevant ones areurban-fashion styled bracelets, offering a wristband comprising aplurality of feedback devices arranged around a circumference of thewristband and is positioned on a narrow area of the hand—the wrist.However, in the intense context of real life the hiker, athlete orsoldier act in, they practically cannot differentiate between theconcentrated vibrations and thus to translate the vibrations to actualdirections; as the vibrations are limited to a too narrow area on thewrist.

In sharp contrast with the prior art devices, the devices and systems ofthe present invention guide and lead the user thereof, such as a hiker,hunter, athlete or soldier, sight-disabled person, to his/herdestination without distractions, as well as with optimizedconsiderations to the extreme circumstances and conditions the user isexperiencing.

The forearm wearable navigation devices of the present invention,separate, distinguish, differentiate and simplify the navigationindications/instructions to the user and thus creating an intuitivenavigation experience.

The devices of the present invention provide sensation-based directions.As illustrated herein, there are micro-vibrators placed on the tip ofeach directional arm. The vibrations are ergonomically funneled to aspecific point on the users forearm, resulting in a feel of a firmpointed touch on the skin, as if someone were poking the user's skin.The device also provides one or more visual indications, which can bedisabled, by embedded LED emitters in each directional arm.

Materials of construction of the device—there are several cover(“shell”) types. textile, silicone, rubber or a combination thereof.These provide the device with flexibility, durability, water resistance,light-weight and a slick look.

Team usages of the systems of the present invention (see FIGS. 12). Whena “split” occurs in a team of users, the leader and the detached/lostuser will both get a “Stop” alert (all vibrators at once) twice (aunique alert to this scenario). When the team regroups, the detacheduser will receive a “Calibration” alert. The leader receives a“Calibration” (full cycle of vibrations) alert and a directional alertsimultaneously, to indicate and lead the leader to the next waypoint.

Integration to external devices: the unique vibrations' language,created by the systems of the present invention, enables creation ofadditional alerts to indicate of additional scenarios and necessities.For example, alerting on a too fast heart's pulse-rate will alert theuser by a slow pace vibration, instructing him/her to slow down.

The app supports creating on-the-go landmarks (Touch-and-Go        on a button on the device)        -   a. Places a pin on the map        -   b. Can be shared with social networks        -   c. As a landmark is set, there is an indication by an            all-around-vibration and by a light on the center LED.            -   i. The app is connected to the physical device—the                forearm navigation band—by P2P wifi or Bluetooth            -   ii. The app provides data to the device that is                presented on its screen, such as, but not limited to a                current time, compass, azimuth, temperature (C or F),                altitude (measurements—US or Eu, set in apps' settings),                longitude/latitude, speed, terrain/route steepness                (elevation profile), distances, from start point, from                last waypoint, to next waypoint and to last                waypoint/destination, time from start point, from last                waypoint, to next waypoint and to last                waypoint/destination        -   d. The app is constructed to receive data from the device,            such as, but not limited to, receive location trigger data            to create a landmark. When a landmark is set, a waypoint is            created on the route and there will and indication, a green            LED blinks.    -   8. Based on the speed of the walk/run the app will alert the        user a bit before a required turn in order for him not to miss        the turn—with several short vibration flicks and light flicks on        the relevant directional device's arm    -   9. The app store historic navigation data such as time,        duration, average duration per section if the trek.    -   10. The app supports all relevant features relevant for        navigation provided by the SDK.
